Tridonic Introduces DC-String 48V Track Lighting Technology to the US Market

Tridonic, specializing in smart and efficient lighting solutions, announced its new DC-String technology, the DC String is now commercially available with a new 100-watt AC/DC power supply designed for the US market. The AC/DC driver and the DC/DC board are intentionally separated, the innovative 48V DC-String lighting solution does away with bulky track boxes, leading to a slimmer design. The DC-String technology gives luminaire manufacturers a new freedom of design and provides simplicity, a lower cost to wire, and use of familiar lighting controls with a 0-10V bridge, which allows for safe interchangeability for occupants in the space.

Ease of Use

Thanks to DC-String technology, users benefit not only from designs with local dimming convenience, called localDIM, but also from dimming with the aid of a 0-10V bridge to enable lighting control on a familiar platform for different uses in day and night applications. In the past, rail or metal-extruded track lighting systems required additional circuitry and conductors for multiple control channels and/or multi-dimming functions. With DC-String, the system cost savings comes from using two wires and conductors instead of the five conductors normally used in these track applications. And for those instances where users want to move a luminaire to another location, the hot plug allows easy and safe removal and replacement of those luminaires without having to switch off the primary power.

Flexible, Aesthetic Design

DC-String technology offers OEMs unique options for luminaire design and miniaturisation. Tridonic has now ensured that spotlights and track heads will make a positive design impression because there is no visible track box. Ultimately, the benefits come from optimized light output, as well as miniaturization and aesthetic design capabilities that are ideal for lighting applications in retail, hospitality, art galleries, museums and residential niches.

Central Driver for Multiple LED Light Sources

With DC-String, Tridonic's ingenuity reorganizes power supply performance and signal transmission for LED spotlight and track lighting applications. The central AC/DC driver efficiently supplies 48V power to multiple luminaire bodies. This efficient design is maximized due to the DC board both supplying the LED module with its required power and serving as a control interface, all done in a small package with big performance.
